Rolls-Royce will carry out an inspection of the Package B engines, which are used by Boeing, but said the problems will not prevent it hitting financial targets for the year.

In a statement, the company said: "We have therefore agreed with Boeing and the relevant regulatory authorities to carry out a one-off inspection of our Trent 1000 Package B fleet, to further inform our understanding.

"The Package B standard has been in service since 2012 and consists of 166 engines."

In March, the group found components were wearing out sooner than expected on up to 500 Package C Trent 1000 engines.

It booked higher costs from bringing forward an inspection programme, but brought down its discretionary spending to keep in line with targets.
